Long Pulse ND:YAG Laser (1064&532nm)was absorbed selectively by
haemoglobin , Follicular bulb and prominent part of hair follicle.
However, the surrounding normal tissues absorb very less or none,1064&532nm laser can penetrate epidermis into the target blood
vessel, Follicular bulb and prominent part of hair follicle. With
sufficient Energy density from YILIYA-1064A and YILIYA-1064B laser
, it can damage the target blood vessel and follicle tissue without
hurting epidermis. Meanwhile , good epidermis cooling technology
make high energy density to the skin possible.
